Step 1: What I Used

(Sorry not all items are in these pictures)

Materials:

ÃÂÃÂ¢ÃÂÃÂÃÂÃÂ¢2 plastic pizza trays (I got these from fridge pizzas I had got, but you could use wood)ÃÂÃÂ¢ÃÂÃÂÃÂÃÂ¢ mobile phone case which you aren't afraid to ruin!ÃÂÃÂ¢ÃÂÃÂÃÂÃÂ¢some metal rods (I actually used rods from a Meccano kit I had and I used a few other but and bobs from this set)

Tools:

ÃÂÃÂ¢ÃÂÃÂÃÂÃÂ¢scissors (I actually use a Stanley knife because I broke my scissors)ÃÂÃÂ¢ÃÂÃÂÃÂÃÂ¢super glue (I had to use PVA because I ran out but it works just the same) ÃÂÃÂ¢ÃÂÃÂÃÂÃÂ¢low tack tapeÃÂÃÂ¢ÃÂÃÂÃÂÃÂ¢rulerÃÂÃÂ¢ÃÂÃÂÃÂÃÂ¢drawing compass ÃÂÃÂ¢ÃÂÃÂÃÂÃÂ¢pencilÃÂÃÂ¢ÃÂÃÂÃÂÃÂ¢Popsicle stick to spread the glue

Step 2: How To Do Make It

I glued the 2 pizza dishes together (I used the low tack tape to keel them aligned). I then found the centre using the technique above on another tray. Then draw on 3 rings using the compass but leave a small gap between them because they will have to move past each other!

NOTE: the smallest ring must have a diameter slightly larger than the length between diagonal corners on your phone case!

Step 3:

Insert rods through the rings as shown by red lines in the photo. If you have done it right it should work like the the photo that followed.

Step 4:

To attach my phone I made a small structure which I attached to the make of my phone case ten screwed the structure onto the inner most ring.

Step 5:

I strengthened the rings with some of the Meccano as my iPhone 4s isn't very light compared to other phones. I then made a temporary stand to hold the rings out of the remaining Meccano and attached them to yet another pizza tray. (But you could use wood)
